Angelina Jolie has a secret - and it's so secret that even her partner Brad Pitt doesn't have access to it.  It's so "intimate" that she's not shared it with anyone and probably never will.

Angie has been keeping a pregnancy diary throughout the last few months - the actress wants to remember every single detail and the emotions she's experienced during this exciting and trying time.

A pal said, "While she's been stuck on bed rest, Angelina is writing down all the changes she's going through physically and emotionally.

"This journal is very special to her and she's keeping it private, even from Brad. She said that maybe she'll let him see it one day, but for now it's just for her. She needs to have an outlet where she can vent -- sometimes about Brad!"

I think most women have done that - I know I did with my pregnancies.  It's something you want to look back on years after your children are born, because let's face it, you forget a lot of stuff.  Kids do that - suck your brains out - ha.

According to the National Enquirer's source, Angelina has been "constantly worrying about bringing the twins to full term and even has a huge calendar on the wall where she marks off everyday.

"She desperately wants them to be as close to term as possible.

"The whole family feels very caged in. It's a hothouse of emotion and anticipation, and Brad keeps doing what Angie calls a 'bolt', where he takes off. They had words the other day because Brad was going somewhere on his own and she screamed 'Are you doing another bolt?'"

Yup, that's what I say to my husband when he's going out - doing another bolt are you?  Because regular people talk that way - wait, Angelina Jolie isn't regular people.  My bad.

The friend added, "She has days when she's so annoyed with him, but then she says how bad she feels for being such a bitch!"  Yay, Brad and Angie argue just like normal folks!

"Angie jokes in the journal that she's ready for her twins to 'just come out and get it over with'.

"She's still totally amazed that she's having twins. She daydreams in her journal about how they'll look and how they'll sound and worries about whether they'll be healthy."

See?  Angie's just like us non-famous moms - except richer, and she has sex with Brad Pitt, for realz.
